<em><u></u></em>
<em><u>2x=26</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>x=13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>So the first number must be 13</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>13+y=18</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>y=5</u></em>
<em><u></u></em>
<em><u></u></em>
<u><em>And the second number must be 5</em></u>
Fill in x=1.7 gives f(1.7) = 0.5*1.7 ≈ 0.850
Answer:
(2, 4)
Step-by-step explanation:
The only point that satisfies the inequality is (2, 4).
(0, 5) : -0^2 +5 = 5 . . . . . not > 5
(1, 3) : -1^2 +5 = 4 . . . . . . 3 is not > 4
(2, 4) : -2^2 +5 = 1 . . . . . . 4 is greater than 1, so this point is in the solution set.
You can first distribute the number into the parenthesis: 3n + 2 - 8n. Now, combine the like terms (n): -5n + 2. It can either be -5n + 2 or 2 - 5n.
